Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a side clutch switching operation device in a management machine, in which both side clutches can be operated in the same operating manner when a handle is transferred.

[Conventional technology]

Conventionally, in a management machine in which handles with side clutch levers on both grip sides are freely transferable in the front-back direction of the machine body, both side clutches can be operated in the same operating procedure as the handles are transferred. The thing is seen in Japanese Utility Model Publication No. 60-27093.

[Problems to be solved by the invention]

However, in such a structure, since the clutch linkage state is selectively switched by the movement of the sliding shaft, the engagement change due to the switching becomes uncertain, the structure becomes complicated, and the manufacture and assembly are also difficult. There is a problem in that it is difficult, and the dimension of the wire requires precision, and it is difficult to deal with elongation after use.

[Means for solving problems]

The present invention solves such a problem, and has a simple structure and is capable of surely switching and changing. Therefore, the switching case (A) connected to the handle (3) is provided. Supporting rectangular tube (1
2) The interlocking plate (5) is connected to the supporting angular shaft (13) slidable inside via the vertical pivot (4), and the shaft (14) is connected to the interlocking plate (5).
And the switching interlocking plate (6) is fitted to the shaft (14) to bring the interlocking plate (5) and the switching interlocking plate (6) into contact, and the switching interlocking plate (6) The interlocking plate
The connecting pieces (15a) and (15b) on both sides in the left-right direction of (5) have both side clutch wires (8a) and (8b) extending from the mission case (7) side and extending from the front part of the switching case (A). ), Respectively, and extend from both side clutch levers (2a) (2b) side to the connecting pieces (17a) (17b) on both left and right sides of the switching interlocking plate (6), and the switching case (A ) Both operation wires (9a) and (9b) extending from the rear part are interlockingly connected to each other.

[Action]

Therefore, if one or both side clutch levers are operated, one or both side clutch wires can be operated via the interlocking plate and the switching interlocking plate. By rotating the plate about 180 degrees with respect to the interlocking plate, both side clutches can be operated in the same manner by operating both side clutch levers in the same operating procedure.

〔Example〕

 Next, an embodiment shown in the drawings will be described.

Fig. 2 shows a side view of the control unit. Both wheels (10a) and (10b) are mounted on both sides of the lower part of the mission case (7) which is in the vertical direction, and from the middle of the mission case (7) in the vertical direction. Both side clutch wires (8a) (8b) for operating the side clutches of both wheels (10a) (10b) are extended upward,
It is installed so that it can be transmitted from the front engine (E) through the belt cover (11) to the mission case (7), and the upper handle (3) is located behind the handle frame (3a) on both handle rods (3b). And the handlebars (3
b) Side clutch levers (2a) (2b) are installed below the left and right grips (1a) (1b) at the rear end of the rear end, and the base of the handle frame (3a) is located above the mission case (7). A handle (3) is reciprocally movable in the front-rear direction of the machine body so as to be rotatable, and is constructed in the same manner as the conventional structure.

A switching case (A) is connected in the middle of the handle (3),
A supporting square tube (12) extending in the front-rear direction is fixedly provided on the inner front part of the switching case (A), and a supporting square shaft (13) slidably fitted in the supporting square tube (12). The central front part of the interlocking plate (5) is pivotally attached to the rear end of the interlocking plate (5) via a vertical support shaft (4),
A switch interlocking plate (6) of the same size is joined to the back surface of (5), and a shaft (14) protruding from the center rear part of the interlocking plate (5).
The center boss (6a) of the switching interlocking plate (6) is rotatably fitted to the switching interlocking plate (6), and both side clutch levers (15a) and (15b) on both sides of the switching interlocking plate (6) are engaged. Connect the rear ends to 2a) and (2b), and the upper and lower wire receivers (16
a) Connect the front ends of both operation wires (9a) (9b) extending from (16b), respectively, and connect the connecting pieces (17a) (1) on both sides of the interlocking plate (5).
7b) includes wire holders (1
The side clutch wire (8a) extending from 8a) and (18b)
The rear ends of (8b) are connected to each other.

Further, on both sides of the switching case (A) on both sides of the shaft (14), two long grooves (19a) and (19b) in the front-rear direction are formed, respectively, and at the top of the switching case (A), there are both sides. Long groove (19a) (1
9b) is formed with a lateral groove (19), and the base of the lever (20) that can be fitted into each groove is connected to the connecting piece (15a).
It is configured by being fitted and fixed to the side portion of the switching interlocking plate (6) in the vicinity of.

Therefore, as shown in FIGS. 2 and 3, the handle
In the normal state in which (3) faces forward, as shown in FIGS. 1, 4, and 6, the lever (20) is inserted into the long groove (19a) side and the switching interlocking plate (6) is rotated. Switching interlocking board
The connecting pieces (15a) and (15b) of (6) and the connecting piece (17) of the interlocking plate (5).
a) and (17b) will be located in the front and back respectively,
When the right side clutch lever (2b) is operated, the side clutch wire (8b) is turned to the arrow (a) while rotating both plates (5) and (6) around the spindle (4) as shown in FIG. You can pull it in the direction to operate the side clutch of the right wheel (10b).

If you operate the left side clutch lever (2a),
The side clutch of the left wheel (10a) can be turned off while operating the side clutch wire (8a) by operating as shown by the phantom line in FIG. 7, and the both side clutch levers (2a) (2b) can be operated. When operated at the same time, pull both side clutch wires (8a) and (8b) at the same time while moving both plates (5) and (6) in parallel with the support angular shaft (13) as shown in FIG. Thus, the side clutches of both wheels (10a) (10b) can be turned off.

When the handle (3) is transferred to the front of the machine as shown by the phantom lines in FIGS. 2 and 3 and set backward, the lever (20) is moved from the long groove (19b) as shown by the arrow (b). When the switching interlocking plate (6) is rotated 180 degrees by moving it into the groove (19), the connecting interlocking plate (5) connecting pieces (15b) and (15a) and the interlocking plate (5) connecting piece (5). 17a) and (17b) will be switched to the front and rear positions respectively, and when the left and right side clutch levers (2a) and (2b) are operated while the aircraft is moving backward, it is shown in Fig. 10. Thus, the side clutches of the wheels (10b) and (10a) on the left and right in the forward direction can be operated, and can be operated at the same time.

[Effect of device]

Thus, according to the present invention, the switching interlocking plate (6) can be satisfactorily connected and switched by simply rotating the interlocking plate (5) about 180 degrees with respect to the interlocking plate (5). Even if the direction is switched, the left and right side clutch levers (2a) and (2b) can be used to easily operate the left and right side clutches in the forward direction of the machine in the same operating procedure, and the connection state by switching does not change and is good. It has a feature that it can be suitably implemented with a simple structure that facilitates manufacturing and assembling.
